In the improvement V-disclosed herein. l am to fuse the pressure members heretofore used :in the die '1 for prelimnarily forming or producing the smooth edge portions a and b of the surfaces c and d to be ornamented and then followingl the Vlast Y ornamenting set of thesurfaces yof thev clay column, to-,com-

plete With suitable Vtools the smooth surfacesA a and b. VIt has been found. in practice that.

- due to thefswellingand. delection in. size of. thel clay column the initial formingiof the smooth cornersor edges Will not always remainA in a finely finished state, if subse. quentlyv ornamented, and' that the ornamenting step, if there is any deflect-ion or irregulari'ties in theclay column will destroy the effectiveness andiinished appearances ofsuch smooth surfaces.

The appliance'for producing the finish side surface CZ isarranged in duplicate vand supported to act on the lower l'edges of the claycolumn,'preferably after the same has been severed into units of brick, to produce the linished smooth surfacesrv adjacent the lower edges ofthe yor'namented side surfaces `d.
